bit_user The article said: 320KB of usable SRAM and 384KB ROM. It's a bit of a stretch to call this a "computer", in this day and age. Yes, I know early PCs had about that amount of main memory and probably even less ROM, but that was almost 45 years ago. I rather think of something as a "computer", if it supports a general-purpose OS and general-purpose applications. Anything smaller is a "smart device", but not something you could generally use as a computer. Reply

DIY vs. commercial, though. When it comes to stuff like this, a hobbyist is at a big disadvantage compared with a company that can do custom manufacturing of highly-engineered products. Reply

JRStern Go crazy and make it 4mm thick but make it awesome. Maybe you can slim it down later if there's any real reason to. Reply
